A recent research has suggested that speaking to a friend when infected with the virus could be just as dangerous as coughing close to them, thanks to lingering particles. Deadly Aerosols Droplets containing the virus are typically spread when an infected person speaks, breathes and coughs. Large droplets eventually fall to the ground over short distances, but tiny droplets called aerosols are able to carry the virus over distances greater than two meters.   Experts have now developed models to investigate the risk posed by large droplets and aerosols and look for ways to mitigate it. Their findings indicate that it takes only a few seconds for expelled particles to travel beyond two meters.   According to Prof Pedro Magalhães de Oliveira, an expert in fluid mechanics at the...
